DATEDIFF working days between 2 dates

[Anonymous]

Hey all,

I've followed the "DATEDIFF Working Days" instructions for calculate the working days. In fact, I have a table with all the days and a "1" in the saturdays, sundays and holidays ("0" on work days). But I'm not getting what I want. Could you help me?

Also, I have a table like this:

ID	Start Date	Final Date	DATEDIFF	DATEDIFF1
123	01/01/2018	02/01/2018	1	?
124	05/01/2018	10/01/2018	5	?
125	15/01/2018	01/02/2018	17	?
126	18/01/2018	20/01/2018	2	?

I got a DATEDIFF between dates but I want the DATEDIFF discounts the saturdays, sundays and holidays. I thoght about calculate how many saturdays, sundays and holidays are between start and final date and then rest it in DATEDIFF column. But I don't know how I should say it to PowerBI.

Yes! It worked for me.

In your example you only have 1 holiday (25/12/2017). I'm trying to add more dates; 26/12/2017, etc.

Just a quick question, in order to add more holidays, you need to add them in both places (table and formula). Is it right? I thought it should be added only in the table and then the formula gets all these holidays.

No, you should just have to add them in one place. I used a DATATABLE in the measure, just so that everything was contained in the measure itself. In practice, I would expect that you would have a separate table of holidays and you would just load that into the holidays var like this:

NetWorkDaysHolidays = 
VAR Calendar1 = CALENDAR(MAX(NetWorkDays[created date]),MAX(NetWorkDays[review date]))
VAR Holidays1 = 'HolidayTable'
VAR Calendar2 = EXCEPT(Calendar1,Holidays1)
VAR Calendar3 = ADDCOLUMNS(Calendar2,"WeekDay",WEEKDAY([Date],2))
RETURN COUNTX(FILTER(Calendar3,[WeekDay]<6),[Date])

In this case, you would have a table called "HolidayTable".

Hi again Greg,

I followed your instructions but Powerbi doesn't find the table. It seems I have to write a measure in "VAR Holidays1 =" but the table with all the dates are not allowed:
